I really want to change out the old 2.73's, but dont have the tools or experience to change out the ring and pinion. so, the only alternative i see is to swap the whole rear end with one that has the gears I want. what cars will have this rear end without doing too much modification besides other 94-95 mustangs. I saw a thunderbird coupe rear end with 3.73's on the local craigslist here for $300. it didn't say what year though. any info or suggestions would be greatly appreciated. thanks
